It's not many of us who were organized enough to tape ourselves at age 12 talking to the future us, but thank goodness Jeremiah McDonald was. Now that it's 20 years later, he's having a little conversation with his past self. The results are pretty amazing, though the exchange between the two (er, one) is more contentious than you'd think. It seems you annoy yourself just as much in the future as you did in the past.
